Sir, I am working with reactive power optimization. If I run GSA algorithm without adding penalty terms, my power loss is less compared to the original system. But if I add penalty terms for voltage violation(PQ buses), line flow violation, reactive power violation(PV & Slack) and slack bus real power violation, my power losses are high compared to without penalty. (Without using Enforce Qlimits). What is the reason and how to correct it? To correct this, I tried the following.
With Enforce Q limits set to 1, error occurs in setting ref bus. With Enforce q limits set to 2, no error occurs but with very low value of power loss compared to without penalty? My program is correct or not? What is the difference between Enforce Q limit set to 1 or 2? from ambika
